exposes an ore-bed, showing three streaks of ore, respectively 

 7^, 4^, and 2 feet in thickness, separated by a gneissoid 

 material, probably a local horse. The dip is 40° S. E. 

 The ore is a compact magnetite in a gangue of hornblende 

 and epidote.

Between here and Helton creek, a distance of about one- 

 quarter of a mile across, is the Red Hill property, over 

 which a number of openings have uncovered a rather in- 

 tricate and distributed ore-formation. 



The main opening. No. i, is a trench through the comb 

 of the hill, over 200 feet in length, through a decomposed 

 schistose and argillaceous material, carrying almost through- 

 out its entire extent mixed masses of soft ore, hard ore, 

 and crystalline sandy ore, distributed irregularly through 

 the gangue; it is evidently one of the broken-down re- 

 deposits, before alluded to. 



At the eastern end of the cut some pyrites was mixed 

 with the material. An analysis of an average sample 

 shows:

Silica 19-83 



Metallic iron 51-55 



Sulphur --- 0.137 



Phosphorus 0.042 



Opening No. 2, about 30 yards W. S. W. from the above, 

 exposes a solid bed of magnetite in epidote and quartz, 

 over five feet thick, dipping south-east. No pyrites was 

 observed here. An analysis shows: 



Per Cent. 



Silica 31.26 



Metallic iron 36.21
